What's the climate like in Canberra? It has been entangled between warm sea and sub-hot season for a long time ... why is there no temperate monsoon climate in North America?

Canberra is located at the junction of these two climates, and it is barely divided into subtropical monsoon humid climate. The climate in this area is different from that in East Asia monsoon, and the difference of thermal properties between land and sea is not as obvious as that in East Asia, so the temperature and precipitation are not as obvious as that in subtropical monsoon, with small annual temperature difference and relatively uniform precipitation. We call it subtropical monsoon humid climate. The vegetation type in Canberra is evergreen broad-leaved forest.

The reason why there is no temperate monsoon climate in North America (personal summary)

1. Compared with the Asian high controlled by a cold high in winter, there are scattered centers in North America in winter (refer to P39, the distribution of sea level isobars in old people's education edition 1 month), and the winter wind is not obvious; However, in summer, the influence scope and influence of the North American depression are not as large as that of the Asian depression, and the obvious summer monsoon will not be formed as in Asia, that is, the difference in thermal properties between land and sea is small.

2. The topographical features of North America make the ocean air flow between the north and the south unimpeded on the central plain, and at the same time increase the oceanography of the climate in North America, that is, there is no obvious difference in seasonal precipitation, and there is great uncertainty.

3. The blocking effect of Labrador Plateau and Appalachian Mountains in the east on the summer monsoon, and the decrease of temperature and humidity of Labrador cold current also limit the formation of temperate monsoon climate.
